Targetted discharge of dosed quantities of solid materials contained in a gas using a venturi nozzle and a control device for regulating it

摘要

The invention relates to a method and device for the selective discharge of metered quantities of solids which are finely distributed in a gas using one or more controlled venturi nozzles for the purpose of applying lubricants and separating agents to the loaded surfaces of pre-forming tools in pre-forming machines or for applying solids which are finely distributed in a gas to solid carrier materials, in particular in the area of medicines, foods or catalytic converters.
